Drees & Sommer has been overseeing the construction of the building complex for the North Rhine-Westphalian State Agency for Nature, Environment and Consumer Protection (LANUV) in the German city of Duisburg since 2012. This building is the 5,000th project certified by the German Sustainable Building Council (DGNB), and it has now been awarded Gold status in an official ceremony.
The building complex covers a total of 16,500 square meters of rental space. This includes office space, conference and event areas for 400 employees. In addition, 80 laboratories provide sufficient space for research with a focus on water protection. A large photovoltaic system on the roof ensures that energy requirements are reduced. The offices are heated with district heating and supplied with rainwater collected on the roof. Thanks to the high energy standards, the structure achieves almost passive house standard. This means that it falls below the energy saving supply by less than 50 percent.
Drees & Sommer undertook the feasibility study, project and commissioning management and general contractor controls. In this way it contributed to on-schedule and on-budget realization. Drees & Sommer experts were also instrumental in obtaining Gold rating from the German Sustainable Building Council (DGNB) and from Leadership in Energy and Environmental Design (LEED). The project was realized by Aurelis Real Estate.
